I’ve done several fasts, up to 20 days, and have been using IF since Feb of 2016. I’ve wanted to use the fasting mimicking protocol but just haven’t gotten around to it.
Wife decided to fast Wed-Sat (she’s got a lot of experience at this as well) but I was not ready to join her as I was still recovering from a long workout and wanted to keep my intake high to aid in recovery. I had planned to join her today (friday) and fast until Sat evening.
Yesterday, I was not hungry (as many of us eating high fat have experienced) so went ahead and skipped all food until the afternoon, when I had coffee with heavy cream, then, a few hours later, had two eggs and an avocado fried in bacon grease, with salt.
Now, here is the interesting thing, I feel just the same as if I’d gone with zero intake. My head is more clear today, my energy is ok (though I woke up tired as usual when fasting, it just takes me longer to get moving) and I slept like a baby last night.
This is one single data point and I plan to play with the protocol more but for now, I’m thinking we might be able to get some/many of the physical positive aspects of fasting (clear mind, better sleep, extra energy) without going water/black coffee only. I know Longo has done research on it, I am glad to see that, for me, the science “works” in reality.
